Technical Field

[0001] This utility model relates to the field of children's dining chair technology, and in particular to a dining chair with a tray folding mechanism. Background Technology

[0002] A high chair is a chair designed specifically for infants and toddlers, typically to make them sit more safely and comfortably while eating. Some high chairs come with a tray to hold food so that children can sit and eat.

[0003] For example, the "children's dining chair" with patent publication number CN113331632A includes a support frame, a seat and a tray. The upper end of the support frame has an installation position. The seat is detachably installed at the installation position and connected to the support frame. The rear end of the seat has a backrest, which can be tilted. The tray is movable at the front end of the seat and cooperates with the backrest to form an adjustable seating space.

[0004] However, in the existing technology, for high chairs with built-in trays, the tray needs to be opened before sitting down. However, very young children cannot sit down on their own and need to be held by their guardians and placed on the table. Since it is difficult for the guardian to manually open the tray while holding the child, it is very inconvenient to use. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology of dining chairs with built-in trays, where the tray needs to be opened before sitting down, and young children cannot sit down on their own. Guardians need to hold the children and place them on the table. Since it is difficult for the guardian to manually open the tray while holding the child, it is very inconvenient to use. Therefore, this invention proposes a dining chair with a tray folding mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dining chair with a tray folding mechanism, comprising chair legs and a seat, with armrests fixedly connected to both ends of the seat, a tray installed between the two armrests, one end of the tray being provided with a torsion spring pivot, and the other end of the tray being provided with a self-locking component, the tray being rotatably connected to one of the armrests via the torsion spring pivot, and the tray being engaged with the other armrest via the self-locking component, a control component being provided on the bottom crossbar of the chair legs, and a traction rope being connected between the control component and the self-locking component, the control component controlling the unlocking of the self-locking component via the traction rope.

[0007] Preferably, the control component includes a button and a slider, wherein the button controls the slider to slide horizontally by pressing down.

[0008] Preferably, the control assembly further includes a sliding cover and a base, the base being fixed to the outer wall of the chair leg, and the bottom end of the sliding cover being slidably connected to the top end of the base.

[0009] Preferably, a compression spring is fixedly connected between the sliding cover and the base, and the slider is slidably connected inside the base.

[0010] Preferably, the self-locking component includes a card holder and a card block, the card holder being fixedly connected to the bottom of the plate, and the card block being movably connected to the outer wall of the handrail.

[0011] Preferably, the handrail is provided with a limiting cylinder inside, a sliding block is slidably connected to the inner wall of the limiting cylinder, a sliding inner seat is connected to the outer wall of the sliding block, and a spring is provided between the sliding block and the inner wall of the limiting cylinder. The sliding block is moved closer to the inner wall of the limiting cylinder by the pulling of the traction rope. When the traction rope is slack, the sliding block can be reset to its original position by the spring.

[0012] Preferably, the outer wall of the handrail has a horizontal groove at the position of the locking block, the locking block is slidably connected to the inner wall of the horizontal groove, and the locking block is slidably connected to the inner wall of the sliding inner seat.

[0013] Preferably, one end of the limiting cylinder is provided with a wire slide, and the traction rope passes through the inside of the wire slide and is fixedly connected to the side wall of the sliding block.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, when a user is holding an infant and sitting down, the user can open the sliding cover on the chair leg by using their foot, and then press down on the button. The inclined surface of the button controls the slider to move horizontally, which pulls the traction rope. The traction rope then controls the movement of the sliding block, which in turn controls the movement of the locking block. This causes the locking block and the inner groove of the locking seat to be misaligned, thereby unlocking the locking block and the locking seat. This helps the user unlock the tray without using their hands, making it convenient for the user to open the tray and place the child on the seat while holding the child.

[0016] 2. In this utility model, a torsion spring-loaded pivot is provided on the left side of the plate. The torsion spring on the pivot controls the rotation of the plate, achieving the effect of automatic flipping and unlocking of the plate. Springs are provided on the inner wall of the sliding block and the limiting cylinder. When the traction rope is in a slack state, the springs cause the sliding block to reset, so that the card seat and the card block are aligned, allowing the card block to lock the card seat again, thereby fixing the position of the plate. When the user no longer presses the button, the springs allow the self-locking component to return to its initial state, thereby fixing the plate again. Attached Figure Description

[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Example: Figure 1-8As shown, this utility model provides a dining chair with a tray folding mechanism, including chair legs 2 and a seat 6. Both ends of the seat 6 are fixedly connected to armrests 4. A tray 1 is installed between the two armrests 4. One end of the tray 1 is provided with a torsion spring pivot 10, and the other end of the tray 1 is provided with a self-locking component 5. The tray 1 is rotatably connected to one of the armrests 4 through the torsion spring pivot 10, and the tray 1 is locked to the other armrest 4 through the self-locking component 5. A control component 3 is provided on the crossbar at the bottom of the chair legs 2. The control component 3 includes a button 33 and a slider 34. The button 33 controls the slider 34 to slide horizontally by pressing down. A traction rope is connected between the slider 34 and the self-locking component 5. The control component 3 controls the unlocking of the self-locking component 5 through the traction rope.

[0029] Two chair legs 2 are spread out to the left and right and are mounted under the seat 6. The control component 3 is installed on the chair leg 2 near the front. The tray 1 is placed between the two armrests 4. The control component 3 is within the user's foot control range. The tray 1 and the self-locking component 5 are within the user's hand control range. When the user is holding the baby, they cannot directly control the self-locking component 5 to open it, making it difficult for the tray 1 to open from the armrests 4. The self-locking component 5 and the control component 3 are connected by a traction rope.

[0030] Therefore, the opening and closing of the self-locking component 5 can be controlled by operating the control component 3. By using the foot to toggle the switch, when the foot presses down on the button 33, the inclined surface of the button 33 and the inclined surface of the slider 34 are in contact with each other, so that the button 33 pushes the slider 34 to one side. The horizontal displacement of the slider 34 controls the traction rope, so that the traction rope pulls the self-locking component 5 to unlock the switch. The plate 1 has a torsion spring shaft 10 on the left side. The torsion spring shaft 10 has a torsion spring that provides the torsional force for the plate 1 to flip. When the self-locking component 5 is unlocked, the right side of the plate 1 is unlocked, and the plate 1 flips upward, completing the unlocking of the plate 1, thus freeing the hands and helping the user unlock the plate without using their hands. This makes it convenient for the user to open the plate when holding a child and put the child on the seat.

[0031] like Figure 5 As shown, the control component 3 also includes a sliding cover 31 and a base 32. The base 32 is fixed to the outer side wall of the chair leg 2, and the bottom end of the sliding cover 31 is slidably connected to the top end of the base 32.

[0032] Since the self-locking component 5 can be unlocked by stepping on the button 33, the user may accidentally touch the switch by stepping on the button 33 when sitting down, which will affect the stability of the plate 1 and cause food to spill during the meal. Therefore, a sliding cover 31 is installed on the surface of the base 32. The sliding cover 31 covers the surface of the base 32 and completely covers the base 32, so that the button 33 is located in the inner cavity below the sliding cover 31. The protection of the button 33 by the sliding cover 31 prevents accidental activation of the switch.

[0033] like Figure 5As shown, a compression spring 35 is fixedly connected between the sliding cover 31 and the base 32, and the slider 34 is slidably connected inside the base 32.

[0034] In order to enable the sliding cover 31 to automatically cover the base 32, a compression spring 35 is provided between the sliding cover 31 and the base 32. The elastic force of the compression spring 35 is used to automatically reset the base 32 and isolate and protect the outer layer of the button 33.

[0035] like Figure 2 and Figure 7 As shown, the self-locking component 5 includes a card holder 55 and a card block 56. The card holder 55 is fixedly connected to the bottom of the plate 1, and the card block 56 is movably connected to the outer wall of the handrail 4.

[0036] When the plate 1 is fastened onto the armrest 4, the card holder 55 and the card block 56 come into contact with each other. The inclined structure of the card block 56 is used to press it inward. The side wall of the card holder 55 is provided with a groove that matches the shape of the card block 56. When the card block 56 moves to the position of the groove inside the card holder 55, the card block 56 resets and mates with the groove of the card holder 55, so as to achieve the effect of the card holder 55 and the card block 56 locking each other.

[0037] like Figure 7 As shown, a limiting cylinder 52 is provided inside the handrail 4. A sliding block 51 is slidably connected to the inner wall of the limiting cylinder 52, and a sliding inner seat 54 is connected to the outer wall of the sliding block 51.

[0038] A limiting cylinder 52 is installed in the inner cavity on the right side of the plate 1. The sliding block 51 can slide freely inside the limiting cylinder 52. A spring is installed between the sliding block 51 and the inner wall of the limiting cylinder 52. The sliding block 51 is moved closer to the inner wall of the limiting cylinder 52 by the pulling of the traction rope. When the traction rope is relaxed, the sliding block 51 can be reset to its original position by the spring.

[0039] like Figure 2 and Figure 7 As shown, a horizontal groove is provided on the outer wall of the handrail 4 at the position of the locking block 56. The locking block 56 is slidably connected to the inner wall of the horizontal groove, and the locking block 56 is slidably connected to the inner wall of the sliding inner seat 54.

[0040] A horizontal groove is formed on the side wall of the handrail 4. The length of the horizontal groove is the same as the translation distance of the sliding block 51. When the traction rope controls the sliding block 51 to move, the sliding block 51 controls the locking block 56 to move synchronously.

[0041] like Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, one end of the limiting cylinder 52 is provided with a wire slide 53, and the traction rope passes through the inside of the wire slide 53 and is fixedly connected to the side wall of the sliding block 51.

[0042] The inner cavity of the wire slide 53 can accommodate the traction rope, allowing the traction rope to move along a fixed channel, ensuring that the distance the slider 34 moves and the distance the sliding block 51 moves change synchronously.

[0043] The usage and working principle of this device are as follows: The unlocking process for the dining chair is shown in the attached document. Figure 8 As shown;

[0044] In its natural state, the spring 35 controls the sliding cover 31 to move and cover the base 32, using the sliding cover 31 to cover and protect the button 33. At the same time, the plate 1 flips onto the armrest 4, and the locking block 56 locks into the groove of the card seat 55, fixing the right end of the plate 1.

[0045] To unlock, firstly, the user slides the sliding cover 31 to the left with their foot, causing the sliding cover 31 and the base 32 to be misaligned, with the button located under the user's foot; then, the user steps on the button 33 with their foot, and the button 33 uses its inclined surface to press the slider 34, which in turn controls the pulling rope; finally, the other end of the pulling rope pulls the sliding block 51 to move, which in turn moves the inner sliding seat 54, which in turn moves the locking block 56, causing the locking block 56 and the locking seat 55 to be misaligned, thus unlocking the self-locking component 5.

[0046] Finally, the torsion force of the torsion spring on the torsion spring shaft 10 is used to control the rotation of the plate 1, causing the plate 1 to flip upward and open, thus unlocking the plate 1.

[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
